My ballpark figure would be 100-150W idle for the dual xeon setup. Taking out one CPU would probably drop you 30-40W.

Modern Ryzen still isn't very efficient at idle (at least not for me).

If you're really concerned about power cost: get a used SFF business PC like a Prodesk G4 or something. That'll get you idle draw around 10-15W (and chances are the CPU actually beats the Xeon at most tasks).

1.25W/TB

Consumer mobo + 8x8TB spinning + HBA + 10G networking.

Could be better (especially with EU power prices), but in the winter it's not too bad.
